While it may sound unusual, this simple trick can boost your health, improve gardening results, and even enhance traditional cooking methods.

1. Boosts Iron Intake Naturally

• When an iron nail rusts, it releases trace amounts of iron into the onion.

• Onions infused with iron were sometimes added to soups, stews, and broths to increase dietary iron absorption.
  Fun Fact: In folk medicine, iron-infused onions were seen as a natural way to strengthen the blood.

2. Improves Soil Health & Plant Growth

• Onions absorb iron from the nail, enriching them with nutrients.
• Planting such onions in the garden can help replenish iron in the soil.
• Extra iron strengthens plants, reduces yellowing leaves, and helps prevent iron deficiency chlorosis.
  Gardeners often bury iron nails near plants to serve as a natural fertilizer and pest deterrent.

3. Enhances Antibacterial & Healing Properties

• The presence of iron may further boost these healing properties.
• Traditionally, people used onions with nails in folk remedies to purify water or treat minor infections.
  Some believe placing an iron nail in an onion overnight enhances its medicinal qualities.

4. Old-Fashioned Cooking & Pickling Trick
